You can easily specify the column|key to sort on via -k flag ...
{ echo "polka 1" ; echo "dot 4"; } \
| sort -k2,2nr

Allrighty, I employed some awk to get a good enough output:
#!/bin/sh
newline='\
'
pkg_info -as | \
tr '\n' ' ' | \
sed -e 's/Package Size://g' \
-e "s/(1K-blocks)/$newline/g" | \
tr ':' ' ' | \
awk '{print$4," ",$3}' | \
sort -gr | \
head -30
Thanks.

Re: help with shell script
Hi. I am writing up a doc for the fbsd community that covers usage of ports. I have two commands that allow me to assertain the amount of disk space being utilized by currently installed ports. I would like to make a shell script (bourne or bash) out of them but I am not sure how. 1. This gives me the amount of space (kB) taken up by the 10 largest ports: $ pkg_info -as | grep ^[0-9] | sort -gr | head -10 | cut -c 1-6 2. Using one figure from above list I produce the details of the corresponding port: $ pkg_info -as | grep -B3 240695 Output: -- Information for linux_base-8-8.0_6: Package Size: 240695 (1K-blocks) -- I would like the output of the script to be the above but for all ten ports (~40 lines; insert a blank line between each?). I know I need some sort of iteration but I am rusty on scripting. Can anyone help? This should get you close... if you want only the top 10 just add more pipes to the end with sort and head... #!/bin/sh newline='\ ' pkg_info -as | \ tr '\n' ' ' | \ sed -e 's/Package Size://g' \ -e "s/(1K-blocks)/$newline/g" |\ sed -e 's/^ *Information for //' ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
